CVE-2024-28085

wall in util-linux through 2.40, often installed with setgid tty permissions, allows escape sequences to be sent to other users' terminals through argv. (Specifically, escape sequences received from stdin are blocked, but escape sequences received from argv are not blocked.) There may be plausible scenarios where this leads to account takeover.

Skyler Ferrante discovered that the util-linux wall command did not filter escape sequences from command line arguments. A local attacker could possibly use this issue to obtain sensitive information.

USN-6719-1 fixed a vulnerability in util-linux. Unfortunately, it was discovered that the fix did not fully address the issue. This update removes the setgid permission bit from the wall and write utilities.
